Ambassador

The Ambassador API Gateway provides all the functionality of a traditional ingress controller (i.e., path-based routing) while exposing many additional capabilities such as authentication, URL rewriting, CORS, rate limiting, and automatic metrics collection.

Ambassador Addon

Ambassador Operator is a Kubernetes Operator that controls the complete lifecycle of Ambassador in your cluster. It also automates many of the repeatable tasks you have to perform for Ambassador. Once installed, the Operator will automatically complete rapid installations and seamless upgrades to new versions of Ambassador.

This addon deploys Ambassador Operator which installs Ambassador in a kOps cluster.

Note:

The operator requires widely scoped permissions in order to install and manage Ambassador's lifecycle. Both, the operator and Ambassador, are deployed in the ambassador namespace. You can review the permissions granted to the operator here.

Usage

As a kops addon

To deploy the addon, run the following before creating a cluster -

kops edit cluster <cluster-name>

Now add the addon specification in the cluster manifest in the section - spec.addons

addons:
- manifest: ambassador

Note:

If you've already created the cluster, you'll have to run -

kops update cluster <cluster-name> --yes

followed by -

kops rolling-update cluster --yes

to install the addon.

For more information on how to enable addon during cluster creation refer Kops Addon guide.

Deploying using kubectl

After cluster creation, you can deploy Ambassador using the following command -

kubectl create -f https://raw.githubusercontent.com/kubernetes/kops/master/addons/ambassador/ambassador-operator.yaml
